DSCR Formula: How to Measure Debt Service Coverage

Have you ever wondered why a business with a high monthly profit might still get rejected and get a loan? It feels unfair, right? You show the bank your healthy “Net Profit”, but they keep shaking their heads in a no. The truth is, while profit tells them if your business is making money, it does not tell them if you can actually afford to repay a new debt.

In 2026, lenders have moved away from looking just at your balance sheet. Instead, they focus on a single, mandatory metric and medium known as Debt Service Coverage ratio (DSCR). Investopedia defines DSCR as, “ The debt-service coverage ratio (DSCR) is a measurement of a company’s cash flow available to pay its short-term obligations.” This number tells the story of your cushion, how much extra do you have after paying your operating costs but before paying your lenders.

This guide will break down the DSCR formula into simple terms. We will explain how to calculate it, what the different zones mean for your loan eligibility and how you can boost your ratio to secure better interest rates for your business.

What is the DSCR Formula?

At its face value, the debt Service coverage ratio is a measure of your available cash flow against your total debt obligations. You do not need to be an accountant or a CA or even a maths genius to figure it out; you just need two key numbers from your financial statements.

DSCR = Net Operating Income (NOI)Total Debt Service

These contains –

Net Operating Income (NOI): This is your revenue minus all operating expenses (like salaries, rent, and raw materials). Crucially, it is calculated before you subtract taxes and interest. Many people use EBITDA or Earnings Before Interest, Taxes, Depreciation, and Amortization, as a shortcut for this.

Total Debt Service: This is the total amount of principal and interest payments you are required to pay over a specific period, which is like usually a year. This includes your existing loans and the new loan you are applying for.

What is a good DSCR?

After the calculations are done, the results most likely appear in decimal. In 2026, lenders use these common benchmarks to categorise your business’s health.

‍Below 1.0 (Danger Zone): if your DSCR is 0.8, it means that you only have rough income to cover 80% of your debt. You are effectively losing money every month just to stay even with the bank. Lenders see this as a “High risk” and will almost always reject the application.

Exact 1.0 (Break Even Point): This means you have exactly enough oey to pay your debts, even down to the last rupee. While you are not drowning, you have no “safety net”. If a machine breaks or a client pays late, you will miss a payment.

1.25 to 1.50 (The Healthy Zone): This is the “Gold Standard” for most Indian banks and NBFCs. A DSCR of 1.25 means that for every ₹1 of debt, you have ₹1.25 in income. You have a 25% cushion for unexpected costs.

Above 2.0 (The Excellent Zone): this indicates a very strong, stable business. With a ratio this high, you are actually in a great position to negotiate for lower interest rates or even higher loan amounts.

Example of Calculating DSCR

Let us suppose a fictional, made up company called “TechBuild”, applying for an expansion loan in today’s year 2026.

‍Annual Revenue: ₹50,00,000

Operating Expenses: ₹30,00,000

Net Operating Income or NOI: ₹15,00,000

Existing + New Debt Payments on Annual Basis: ₹15,00,000

DSCR = 20,00,00015,00,000 = 1.33

‍Solution: With a DSCR of 1.33, TechBuild has a healthy rank. They earn 1.33 times more than they need to pay their debts, making them an excellent candidate for a loan. This is why Financial Literacy is important.

Difference between DSCR vs Interest Coverage Ratio

There is a common misconception regarding DSCR and ICR being the same, or even synonymous. That is not the case. The difference between them are as follows —

Feature	DSCR or Debt Service Coverage	ICR or Interest Coverage Ratio
What it measures	Ability to pay Total Debt, this includes Principle + Interest	Just Interest Only
What it is best for	Term loans with regular EMI repayments	Interest only loans or lines of credit
What is the Standard Bench	1.25 or higher is preferred	1.5 to 2.0 is usually the minimum
How it is calculated	NOI Total Debt Service	EBIT Interest Expense

Conclusion

Mastering the DSCR formula is a critical skill for any business owner looking to scale in 2026. It moves from your focus of making sales to managing debt capacity. By keeping your ratio above the 1.25 benchmark, you can ensure that your business remains attractive to lenders and resilient. This also makes you look as a credible individual to invest for. It is a win-win situation.

To improve your ratio before your next loan application, focus on levers: increase your Net Operating Income by cutting unnecessary overheads, reduce your total debt service by paying down high-interest short term loans. A strong DSCR is not just about getting the loan from the bank, but rather ensuring your business has the foundation to grow sustainably for years to come.

FAQs

Can I get a business loan if my DSCR is less than 1.0?

You may, but to be honest, it is extremely difficult. A ratio below 1.0 indicates a negative cash flow relative to debt. However, if you have strong collateral or high growth business plans, some Non-QM or Non-Qualified Mortgage lenders might consider you, though interest rates will be significantly higher.

Does depreciation count in the DSCR formula?

The bad news is, yes it does. The good news is, it does so in your favour. Since depreciation is a “non cash” expense, meaning that it shows up on paper but you do not actually write a check for it, it is usually added back to your Net Profit to calculate the NOI. This helps boost your DSRCR

How often should I calculate my business DSCR?

You should calculate it at least one a quarter. This is necessary and important because monitoring your ratio over time helps you spot a declining “safety cushion” before it becomes a crisis.

Do different industries have different DSCR requirements?

Industries with very stable, predictable cash flows, like commercial real estate with long term tenants might be okay with a 1.15 DSCR, yes. Unstable or volatile industries, like seasonal retail or startups, are often expected to maintain 1.5 or higher.

Can refinancing my old loans improve my DSCR?

Yes, of course you absolutely can. If you were to refinance a high interest loan into a lower interest one with a longer repayment period, your Total Debt Service goes down, which immediately, in turn, increases your DSCR.
